Australia could be getting half of its electricity from renewable energy by 2025, even without government subsidies for new wind and solar projects, according to a new analysis of energy industry trends.

Why is it so hard to reach consensus about how to slow climate change? Multiple time lags get in the way: some make it hard to convey the risk, while others prolong the search for solutions.

Over a period in which the Australian economy saw around 600,000 additional people get jobs, employment in the renewables sector has been going backwards.
